The first settler of the name of Rosenberger in Montgomery County was Henry Rosenberger, who came to the Indian Creek valley, in Franconia township, in 1729. In 1739 Benjamin Rosenberger settled in Hatfield township, where in that year he purchased 125 acres of land bordering the County Line at Line Lexington, which he held for five years. Daniel Rosenberger purchased another tract in Hatfield lying along the county Line near the hamlet called Hockertown in 1740.

In the year 1745, Henry Rosenberger, Jr., came in possession by deed of his father's plantation in Franconia township. John Rosenberger settled in Hatfield township and first bought land around where is now that borough of Hatfield about 1749-50.

It is a tradition of the family that the Rosenbergers of Montgomery County, PA., came from Germany, from a place called "Zweibrucken" (two bridges). It is supposed that these families that settled in Franconia and Hatfield townships were all related, and while it is certain that Daniel and John were brothers, it is quite evident that the four above mentioned were all brothers and sons of Henry Rosenberger, Sr.

John Shutt Rosenberger, a great-great-grandson of Benjamin Rosenberger, previous to his death is said to have related that one of his ancestors reached the great age of 96 years. It is not now certain which one of his ancestors he named as having reached that age. He also said that one of his ancestors was born on board sip or soon after the landing in America. It is quite certain that neither Benjamin or his eldest son, Yelles, reached the age of 96 years, therefore it must have been Benjamin's father, the emigrant, who was 96 years old at his death. This would also indicate that Benjamin was the son of a pioneer. It is quite likely that Henry Rosenberger, Sr. The pioneer, lived to be 96 years old, but it is not clear that any of the ancestors were born on the voyage over. Benjamin, who no doubt was the eldest, was in all probability born in Germany, and was a lad of from 11 to 15 years old when he came with his father to America. He was born as early as about 1714 and died about 1777, aged 63 years or more. His eldest son, Yelles, was born before 1735 and died 1808, aged 73 or more. The time of the emigration of Henry Rosenberger, Sr., is not known, but was in all probability between the years of 1720 and 1729. The descendants of Benjamin are now largely settled in Bucks Co., PA, and a considerable number also reside in Waterloo County, Ontario, Canada.

All the earlier members of these families belonged to the religious sect called Mennonite and worshipped at Franconia and Line Lexington meetinghouses.

A descendant of Henry's, Benjamin Rosenberger, moved to Canada with his family in 1801. The Pennsylvania German pioneers who traveled to Canada to find reasonable farm land are chronicled in the book, "The Trail of the Black Walnut". They knew that where the black walnut trees grew, the soil was rich and their crops would do well.
